A power amplifier that divides input power among a plurality of parallel channels through a radial line divider, amplifies the power in each channel with three terminal devices, and combines the amplified power in a radial line combiner to produce an output signal. The radial line divider/combiner includes a radial transmission line having a plurality of sectors symmetrically disposed around the inner radius of a supporting annular substrate. The sectors are connected to respective three terminal devices through microstrip transmission lines, and are isolated from laterally adjacent sectors by thin film isolation resistors.
